Estudio geotécnico in Huete

In Huete, the geotechnical subsoil is dominated by the presence of gypsum, anhydrite and salts, which account for more than half of the soil types found in the municipality. These formations exhibit low near-surface permeability, although they may contain significant aquifers at depth. The mechanical properties of the gypsum and salts affect bearing capacity and, in particular, there is a risk of dissolution-related phenomena that can lead to ground subsidence or cavities; therefore, appropriate characterisation is essential for the design of foundations. The occasional presence of limestones and dolomites, together with the low incidence of compacted gravels and sands, usually provides a certain margin in foundation alternatives, always following a detailed analysis of the continuity and depth of these competent materials.

From the seismic standpoint, Huete is located in an area of moderate activity, with 13 significant events over 30 years, although the maximum recorded magnitude is low (Mmax 2), which implies a limited impact on structural design. It is necessary to emphasise the possible existence of karstification due to the gypsum and limestones, and therefore the presence of cavities or conduits must be verified before carrying out any foundation work in order to avoid risks associated with local collapses. In addition, the fact that the subsoil is non-clayey rules out concerns about expansivity-related problems. Thus, the primary condition to be assessed in any geotechnical study in Huete is the possible development of karst processes and the associated dissolution of the gypsum- and salt-bearing soils.
